Game/Movie Idea (OC) (Self Idea)

One idea that I always thought would make a good game or movie is during the initial outbreak in the Arklay Mountains. You play as this Park Ranger who gets a call from cabins and campers that there are monsters in the forest. Then you have to fight your way through zombies and zombie dogs and other bio weapons to save campers and stuff like that. And hell it could even be somewhat open world akin to the Raccoon City section of RE9. It could take place at night and be raining to really build the atmosphere. I think that could be a legitimately terrifying experience (especially in first person mode)
